[MTD] Allow variable block sizes in mtd_blkdevs

2006-11-28T22:27:47+00:00

Currently, mtd_blkdevs enforces a block size of 512, even if the drivers
can seemingly request a different size. This patch fixes mtd_blkdevs so
block sizes other than 512 work correctly.

[MTD] fix printk warning

2006-10-01T16:57:26+00:00

gcc spits out this warning:

drivers/mtd/mtd_blkdevs.c: In function ‘do_blktrans_request’:
drivers/mtd/mtd_blkdevs.c:72: warning: format ‘%ld’ expects type ‘long int’, but argument 2 has type ‘unsigned int’

This could be fixed any number of ways, including use of BUG().
rq_data_dir() only returns 0 or 1, so this entire case is superfluous.
I did the most simple fix.

[PATCH] Split struct request ->flags into two parts

2006-09-30T18:23:37+00:00

Right now ->flags is a bit of a mess: some are request types, and
others are just modifiers. Clean this up by splitting it into
->cmd_type and ->cmd_flags. This allows introduction of generic
Linux block message types, useful for sending generic Linux commands
to block devices.

[PATCH] sem2mutex: drivers/mtd/

2006-03-31T20:18:48+00:00

Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

BUG_ON() Conversion in drivers/mtd/

2006-03-26T16:15:12+00:00

this changes if() BUG(); constructs to BUG_ON() which is
cleaner, contains unlikely() and can better optimized away.

[PATCH] Add block_device_operations.getgeo block device method

2006-01-09T04:13:54+00:00

HDIO_GETGEO is implemented in most block drivers, and all of them have to
duplicate the code to copy the structure to userspace, as well as getting
the start sector.  This patch moves that to common code [1] and adds a
->getgeo method to fill out the raw kernel hd_geometry structure.  For many
drivers this means ->ioctl can go away now.

[1] the s390 block drivers are odd in this respect.  xpram sets ->start
    to 4 always which seems more than odd, and the dasd driver shifts
    the start offset around, probably because of it's non-standard
    sector size.

[MTD] mtd_blkdevs.c: Fix names when many devices/partitions are created

2005-08-04T10:51:18+00:00

mtdblock (and other mtd modules that use the mtd_blkdevs interface
between the mtd translation layers and the linux block layer) handles
incorrectly more than 10 devices or 26 partitions in the names passed to
the generic disk layer.  This causes the device file names and other
info kept by the generic disk/block layers to have names such as
"mtdblock<".  Use integer formatting for device numbers; use "aa-az"
for partitions 27-52, "ba-bz" for 53-78...

[MTD] mtd_blkdevs.c: Remove DEVFS leftovers

2005-08-04T10:50:48+00:00

Remove mtd_blkdevs refs to the no longer functional DEVFS filesystem.

Verified mtdblock continues to work fine via udev with these calls
removed.
